透明的负载均衡器&http正向代理(依赖ares)
1. 灵活的配置
2. 使用红黑树超时管理
3. 全异步模型(双缓存,实现双向同时转发)
4. 多进程工作组
5. 可配置的负载均衡的算法
6. 可以多个分组同时负载
7. 独立的全异步dns
8. 在线工作中配置文件
9. 应用级缓冲池
10. 高性能,低内存消耗

About

透明的负载均衡器&http正向代理 * master-workers架构,http正向代理由独立的dns请求以及缓冲进程 * 使用epoll(ET)模式,采用全异步方式(双缓存,实现双向同时转发); * 事件管理机制(事件池,事件对象分离) * 使用红黑树超时管理 * 灵活且简单的配置文件 * 多种可配置负载均衡的算法 * 实现可以多个分组同时负载 * 不间断在线配置参数功能 * http正向代理实现长连接以及https代理 * 全异步dns解析 spread retract
